Question

prove that acceleration due to gravity decreases as we move towards the centre of earth. what is the weight of the body at centre of earth​

Answer 1

acceleration due gravity. vertically zero horizontal.

Answer 2

as we know that g at depth h below surface of earth is given by

g'=g(1-h/R)

as  by observation we see that as h increases g' decreases

when h=R

g'=g(1-R/R)

=0

where g= acc due to gravity at surface

g'=new acc due to gravity

R=radius of earth
